Smile Heat shields: How well do they work? Pics inside!

After doing my exhaust install this week I completely forgot to install my heatshield. After reading around with 5000 different opinions on how good or bad it is to drive around without your heat shield on I decided to find out. I just happen to have access to a 60 thousand dollar infared camera and decided to take a few shots today after driving an hour and a half home. I'm going to go ahead and post some pics I took after the drive WITHOUT the heat shield. Hopefully this weekend I'll put it back on and we'll recreate the same sitaution and see the difference. I'm also going to take some pics after letting the car idle in place since a lot of people are saying that's when most of the heat soak occurs. Hope this helps clear up any "unknowns" on heatsoaking and everyone finds this interesting, here ya go!

Note: Red = to high for the IR camera to read without setting the range higher (mostly just the turbo is red)

That's great. Looking forward to the pics with heat shields. Should be a noticeable difference...

Will do! Possibly will have the pics of the idling without heatshield tomorrow. The heatshield I'm going to put on is the Cobb heatshield but if the popularity of the thread goes up I may try the cut stocker as well to see the benefits between the two.

It would be really interesting to see pics with a alky system installed.

I doubt you would see much difference in the heat around the turbo. In fact turbo temps will probably be higher on meth because you tend to run more boost.

The pics are very cool - it would be more interesting to see the temps of some of the pieces/parts that are near the turbo, since you will not be able to photog the turbo directly after the heat shield is installed. The intercooler temps will be interesting. Apples to apples if everything else is held constant (which is hard to do).

My test showed the same as your pics. The stock Heat shield didnt help very much on the stock turbo. I used a IR FlexCam T. Using the 20mm 32-662f range.

I have wondered about heatshields. I have a Cobb HS that I had double-coated with JetHot Sterling. Looks great, but seeing it installed I cannot help but think it does little to control heat under the hood. I also have a fully-coated turbo, and I bought a turbo wrap kit but never installed it. It would be VERY interesting to do some direct comparisons among the different HS/coatings/wraps/heat control devices and see how they REALLY shake out!

neat camera...id like to see back to back the heat difference between the metal coolant header tank vs the newer plastic one if it makes that much a difference in radiant heat toward the TMIC. Either way 51-83 C on the endtank is pretty freaking hot.

Heat shields, coatings, wraps all work. Put them together and they do wonders for the TMIC... I have ZERO heat soak and consider my TMIC as good as a FMIC, I can get colder than ambient IAT out of my stock TMIC and into throttle practically any time. That is an increase from 59% efficiency on average to an 85% efficiency on average...with a 93% efficiency when you need it the most on a 40*C day/104*F I got that number...

All great posts, I'll look into doing some shots of some other pieces by request after we finish up with this one, I'm not going to be able to put the heat shield on this weekend but next week I should be able to. I'll keep you guys updated!

Edit: forgot to mention, I'm not sure how much this will affect the heat soak on the IC but I do have open vents on my hood. I'll post a pic of my hood later today but I'm not sure how much this will help in keeping it cool under hood, having a place for heat to escape may be causing slightly cooler temps under hood. Maybe I'll throw the stocker back on for a day to compare hoods as well! Just figured I'd let everyone know the playing field so you can make an even more informed choice when choosing your setup. Also, just picked up an SSAC ebay TMIC so we'll test that as well, stay tuned!

As of lately about 25-30C. Temp around here has been pretty stable. I'll make sure to record the ambient temp next time.

Going to have to move my pics, seems I ate up all the bandwidth of the site I had those posted on. I'll switch them over when I can.

I would be intrested to see these pics I am running my 18 with out a heatshield. I am wondering if it makes a big difference and it's its worth the 50 bucks to put an aftermarket one on.
